KNOCKDOWN MOLD FOR CEMENT G-ARAGES.

Application filed Apri1 7,

Be it known that I, LOUIS Ln Ror SrnLs- HOUSE, a citizen of the United States, residing at Baltimore, in the county of Baltimore City and State of Maryland, have invented certain new and useful Improvements in Knockdown Molds for Cement Garages, of which the following is a specification.

This invention relates to the construction of concrete structures, and has special refer-- ence to a mold for such structures.

More particularly, the invention relates to a mold for monolithic buildings, such as garages and the like, wherein the mold for the entire building may be assembled before starting any of the pouring of the concrete.

The principal and most important object of this invention is to provide an improved and novel mold especially adapted for the molding of monolithic garages wherein the walls, columns, and other parts are all formed from a single block of concrete, the mold being of such character that the different partsthereof are capable of quick and easy assembling to form either a single or double garage with the roof inclined in one way or another as desired, and wherein the assembling of the mold may be readily removed from the formed structure without injury to any of its parts, so that it may be used repeatedly for different structures of like character; the mold parts being also so arranged as to be connected by novel and improved means.

I will now proceed to specifically describe one particular embodiment or form of the invention, and to this end will refer to oer-- tain drawings accompanying this specification by reference characters alike in the several views, and I will then proceed to particularly point out the invention in the appended claims.

In the drawings- Fig. l is a perspective view of a complete mold set up ready for the pouring opera tion.

Fig. 2 is a perspective view of the concrete walls and columns as constructed by pouring in the mold illustrated in Fig. 1.

Fig. 3 is an exploded view of the front portion of the mold showing the manner in which the several parts thereof areassembled.

Fig. 4. is a detail section, with the concrete in place, on the line 4- of Fig. 1;

Fig. 5 is a detail view partly, in section showing the upper part of thefront of the mold.

Fig. 6 is a section on the line 6-6 of Fig. 5.

Fig. 7 is a section on the line 7-7 of Fig. 5.

Fig. 8 is an exploded view showing one of the front corners of the mold partly assembled with the column front plate about to be placed in position. r

Fig. 9 is an exploded view showing the manner of assembling the side boards.

Fig. 10 is a detail section on the line 1010-of Fig. 1.

Fig. 11 is a detail section on the line 11-11 of Fig. 1.

Fig. 12 is a detail section taken longitu dinally through the center of "the mold with the parts so arranged that'the roof slopes from the back to the front, no lintel being employed at the front over the front opening or door opening.

Fig. 18 1s a perspective view-partly broken away showing the manner of asse bling the parts for aidouble garage.

In these drawings, it will be observed that at each of the front corners of the device, there isprovided a vertically extending side mold member 20 having an inwardly off-set portion 21 on the outside of the corner. 'On the inside of each corner is a vertically extending side mold member .22 having off-set portion23, and the main part pf themember 22 is cut away at the top as indicated at 2a to provide for a front beam or lintel connection, as will be hereinafter set forth. a

Projecting from the front edge of each of the members 20 and 22 are vertically spaced headed pins 25' which are properly positioned to pass through keyhole-slots 26 formed adjacent the lateral edges of a vet: tically extending front column mold member 27, tJ-shaped wedges 28 being employed I to fit between the heads of the pins 25 and the face of the member 27 It will be obrests on these bearing strips to form the bottom of the lintel. The sides of the lintel mold are formed by transversely extending mold members 31 which-are set with theirlower edges on the member 30 and which, at their upper corners, have laterally projecting extensions 32. The front side member 31 has these laterally projecting extensions resting on top of the front post or column members 27, and is secured thereto by means of pins 33. Similarly the back or inside lintel side mold member is secured by pins '34 to the members and the extensions 32 crossing over and bridging the space between'the members 20 and the members 22.

On the outer face of the respective extensions or offset portions 31 and 33, there is provided a plurality of laterally extending headed pins 35 for purposes hereinafter to be described. The rear corner of the building is formed by an outer rear corner member 36, which consists of a pair of planks seheaded pins 40, corresponding'in' height to the position of the pins 35. The side walls of the mold are built up of inner and outer longitudinally extending side wall members 4E1, which engage between the edges of the off-set portions 21 and 23 of the front columnmembers and the vertical edges of the members 36 and 38 which face toward the front.

Each of these side members 41 has secured thereto an angle bracket 42 vwhich has a vertical leg projecting above the top edge of the respective member 41, and a horizon; tal leg projecting longitudinally beyond the end edge of the member 41, this horizontal leg being provided with a notch 4E3 on its underside to engage the respective pins 35 and 40. These side mold members are all alike except the top side mold member, which in each instance has an inclined upper edge 44 so as to allow for the slope of the roof, and it will here be observed that these top side members may be positioned, either as shown in Fig. 1 for forming a roof sloping downward toward the back of the building, or as shown in Fig. 12 for forming aroof sloping toward the front of the build in i loreover, the inner member at the top is provided on the face confronting the outer member with a series of wedge-shaped blocks 45 corresponding to the well known core prints in ordinary metal molding. The rear wall of the building is formed by means of longitudinally extending mold members 16, which are provided-with securingbrackets'47, similar in all respects to the brackets e2. It will be observed, at this point, that while angle brackets have been here shown, these being well adapted for the purpose, other bracket forms may be employed.

It will be observed that in the construction shown in Fig. 12, no lintel will be nec essarily employed, and in such event, an angle iron or I-beam may be extended across on top of the member 30, and have its ends bent down to be received into the concrete of the front column or corner posts.

In the form shown in Fig. 13, a double garage is illustrated, and in this form, it

will be seen that there is provided a center post which is made up of two of the members 22, a back post mold 18 being inserted to rest against the front edges of the offsets 23. Naturally, under these conditions, there will be two of the bottom members 30 employed. there is employed a straight outer vertical member 49, and two of the members 38 are utilized with their angles adjacent the space, as shown clearly in the figure. These two members have the space between their for wardly extendingflanges closed by a ver-' Also at the'rear of the building,

placed in position, and the lintel side memhers assembled thereon. Next the lower cores of longitudinal side mold membersvare hooked in position beginning at the bottom, and the same thin is done at the back. Finally, the top side members are arranged in position with the slope of the roof as desired, it being understood that the lintel sides are omitted when the slope of the roof is downward toward the front. In this connection, it should be noted that tie bolts 52 may be extended through the side mold members having sleeves 53 thereon, which are shorter than the distance between such side mold members, so that the bolts may be readily removed and the holes at the ends of.

the sleeves occupied by the bolts filled with a suitable grouting. The proper cement mixture is then poured, and after a suflicient time has elapsed, the mold is removed which will leave a structure similar to that shown'in Fig. 2 having pockets'54 on-its insides at the bottom to receive the roof beams 55, these pockets beingforme'd by the blocks 45. 1

It will be obviouszto engineers and others skilled in the art that constructional changes may be made to suit different sizes and classes of buildings without in any way departing from the inventive principles involved. It will therefore be noted that the embodiment herein illustrated and described is to be taken simply as one embodiment of the invention, and that many such embodiments may be made lying wholly within the scope claimed.
